WORKING PRINCIPLES
Drive code119/92 is a single-phase voltage regulator with tachometer feedback using controlled
diodes (SCR) driven by a system at phase partialization.
The voltage supplying the motor results from an analog process mantaining constant rotations by
meansofthedifferentialcontrolbetweentherealspeedreferencetakenfromthetachymetergenerator
and the one set by the potentiometer or external analog voltage. The coupling with the asynchronous
single-phase high slip Rowan motor gives a variable speed system extremely silent (Absence of
typical PWM whistle) and uniform, from zero to the maximum motor rounds. The application of
controlleddiodesonthepowerpartgivesreliabilityagainstextravoltagesorover-currents.Inaddition,
it is possible to adjust the acceleration/deceleration ramp upon the application needs; the controlled
acceleration ramp works for moving braking loads or irreversible systems only.
Drive code 119/92 gives the possibility to control the speed/torque of the Rowan single-phase motor;
the torque regulation can be done by limiting the maximum voltage on the motor through internal
trimmer P1 or, externally, through potentiometer or 0/+10Vdc signal; for a more precise control of the
motortorque,itisnecessarytoletthecode 119/92 communicatewithotherdevicesworkingatcurrent
closed loop (ex. code 199/92 or code 268).

STANDARDSET-UP
119/92 drives come out of Rowan labs ready tested and set-up for:
-4-pole motors with speed regulation by 3-wire potentiometer (min. 0 rpm - max. 1300 rpm);
-torque limitation not active;
-acc/dec ramp: 2 Sec.;
-S4 microswitch closed (all other microswitches open).
SINGLE-PHASEMOTORSCHARACTERISTICS ANDPOWERABSORBEDBYBRAKEANDCOOLINGFAN
The capacitor within parentheses increases starting torque by
approx. 20% but cannot be used for continual service; its use is
recommended only for intermittent movements.
The maximum current of Rowan single-phase motors is to be
calculated to an approximate value by multiplying the rated value
by 1.5. The same current can be used during the starting phase
or in cycles that require the use for a period equivalent to a
maximum of 20% of the entire work cycle.

voltage of the tachometer generator that is spliced to the motor shaft. It supplies
a direct voltage of 20VDC at 2800RPM that is directly proportional to motor
speed; for this reason, besides being connected to the drive for speed control,
it can be used for analog revolution counters, display counters or other
servomechanisms, provided the overall loading being not lower than 5Kohm
(maxtachometercurrent 5mA).Itisalwaysnecessary,toavoidinterferences,
to connect the tachometer with screened cable.
3-4 VENTILATOR: it is necessary to supply these terminals with 230VAC for the separated ventilation of motor; make sure
that this voltage is present also when the motor is not running, in order to guarantee the max cooling efficiency. As for the
power absorbed by cooling fans, see table on the previous page.
5-6 HEAT PROBE: it is a N.C. contact which opens when the temperature of motor windings exceeds 150°C, safety limit
corresponding to H class (180°C). It is used as emergency for the switching off of RUN remote control switch. The max
capacity of this contact is 1A - 230VAC. (Rowan motor MEC 63 0,15 HP is not equipped with Heat Probe; for this reason
terminals 5-6 are not present in its service terminal board).

BRAKECONNECTION
On request, ROWAN motors can be provided with electromagnetic brake. In this case the motor must be constructed
expressly with lengthened motor shaft and the brake is mounted on the front part, supported by a bell which reproduces
the normal flanging conditions.
There are 2 different types of brakes:
-DIRECT BRAKE: in this case it is necessary to supply the brake to block the motor shaft. This kind of brake is suitable
for precision stops.
-SAFETY SPRING BRAKE: in this case it is necessary to remove supply from the brake to block the motor shaft. It is used
as safety brake in case of lack of main power supply, with suspended loads as overhead travelling cranes, cranes etc.
Both brakes operate with direct voltage 24VDC, for an operating cycle S6 with max 5 'of excitation and 5' of de-excitation
and are supplied through the single terminal or connector placed on the front brake bearing-bell.
For an optimized management of the brake, ROWAN suggests the card code 321S, to be connected as shown below:
The C321S provides a peak of max 34VDC and a subsequent holding voltage of 24VDC. This speeds up the release of
the BRAKE and prevents overheating during continuous service for prolonged periods. For repeated excitations, wait at
least 1 second between de-excitation and re-excitation of the brake.
INSTRUCTIONS FOR CONNECTION and START-UP
Beforepowering,connect tothegroundandsetupthemicroswitchesontheboardtosuitthedesiredtypeofoperation:
-2 or 3 wire speed regulation potentiometer
-inclusion of internal/external torque limitation (see microswitch description)
-2, 4 or 6-pole motor
In case of a 6-pole single-phase motor recalibrate the maximum speed with trimmer P4 until the tachometer dynamo
generates approx. 5.7 VDC with the speed regulation potentiometer or DC signal at maximum value.
- Before powering, adjust the potentiometer or DC signal for zero speed; at power up the motor must be stationary.
Illumination of led L1 (power on) indicates that power supply is flowing through the driving circuits. Turn potentiometer or
increase DC signal: motor speed should increase or decrease according to the set acceleration/deceleration ramp, while
leds L2 (run) and L3 (tachometer gen. presence) must light up accordingly; progressive illumination of led L2 indicates
the presence of voltage in the motor windings, whereas light-up of L3 indicates that the motor is rotating.
- If the motor suddenly races to maximum speed without following potentiometer regulation, and pilot lamp L3 does not
illuminate, it means that tachometer dynamo voltage is not reaching terminals 7 and 8; when this happens, check the
connections again.
- Check attainment of maximum speed and, if necessary, fine adjust the maximum value with trimmer P4; be sure not to
exceed the maximum speed as this would cause the motor to overheat even when loadless; when this happens regulate
P4 until motor consumption equals the value measured at an intermediate speed. In any case check that motor
consumption (measured at power supply line) conforms with the rated value. If during motor operation oscillations take
place due to a particular type of load or due to mechanical transmission, these may be suppressed by regulating trimmer
P7 clockwise; if regulation of P7 were not enough, also regulate trimmer P6 counter-clockwise. To prompt and smoothen
motor response you may close microswitch S5.
Drive 119/92 is provided with a 0,5A protection fuse only for driving circuit; provide external power protection through a
10A fuse for drive 119/92 and 20A fuse for drive 119/92-2HP. Use a shielded cable for control connections (potentiometer,
tachometer generator) especially if they are long stretches or run close to power cables; connect cable braiding to ground
and not to the circuit negative, and only at one cable terminal; the board negative must also not be connected to ground;
at any rate, do your best to avoid routing near power cables or large transformers.
Use relays with contacts for low current for the switching of DC signals on the control terminal panel, and avoid the use
of electromagnetic switch auxiliary contacts for these types of operations.
Drives 119/92 operate efficiently with panel temperatures ranging from -5°C to +40°C; temperatures outside this range
may give rise to faulty operation, speed control drifts and, if temperatures are particularly high, breakdown. Thus place the
boards far from heat sources and provide adequate ventilation to the panel if the environment is subject to high
temperatures.
ISTRUCTIONSFORTHECORRECTINSTALLATIONSASPERTHE ELECTRO-MAGNETIC COMPATIBILITY
STANDARDS(E.M.C.)
Drive Code 119/92 must be powered on through anti E.M.I. filter as indicated in the connection diagrams on page 11; if
more C119/92 drives are installed into the same cabinet we can use a unique filter dimensioned for the total supply
currents. In addition, it is necessary to use a shielded cable to connect the commands (potentiometer, tachometer)
especially when distances are long and we are near to power cables; the cable sleeve must be connected to ground (not
to the negative of the circuit) to one end only; do not connect the negative of the drive to ground; avoid, in any case, the
proximity to power cables or big transformers. Avoid, finally, to create ground loops.

EXAMPLESOFHOWTOCONNECTTHECONTROLTERMINALBOARD
Connection of 2-wire speed regulating potentiometer:
Should you need to use the 2-wire speed regulating potentiometer (as for instance
when replacing Rowan drives of previous manufacture such as old C119) close
microswitch S1 and connect a 10 KOhm potentiometer; speed regulation with 2-
wire potentiometer is not very linear with respect to its rotation.
Selection of different speeds with more potentiometers in parallel:
Two or more potentiometers can be connected in parallel making sure that the
overall resistance between terminals 4 and 6 is not lower than 3 KOhm.

Thepotentiometervalue hasnotto loadthevoltagereference of+10Vdcon terminal

the external potentiometer can be omitted: in this case close microswitch S1 and
limit torque by regulating trimmer P1.

Staticrun:
When the single-phase motor is used in only one direction, and frequent run and
stop operations have to be performed, it is convenient to keep the power supply
electromagnet switch excited and to enable static motor rotation by opening contact
AR connectable to terminals 1-2.
-ByopeningcontactAR,themotorfollowstheaccelerationrampuptothemaximum
speed set and with a ramp time that is adjustable by trimmer P3.
- Closure of contact AR immediately removes voltage, zero-sets the ramp and
switches off RUN led L2.
If motor run/stop were necessary with acceleration and deceleration ramps without
immediately removing voltage from the motor in its stopping phase, perform the
following operations:
- disconnect terminal clamp 5 from the voltage reference to cause the motor to
decelerate to zero revs (or at a minimum speed calibrated with P5);
- connect terminal clamp 5 to the voltage reference to cause the motor to accelerate
to the maximum speed set.
Speed variations are conditioned by the acceleration/deceleration ramp set with
trimmer P3; the controlled deceleration ramp operates with motors applied to
braking loads or irreversible systems, but it is inefficient with inertial type loads.

MAINTENANCE INSTRUCTIONS FOR HIGH SLIP ROWAN MOTORS
“HIGH SLIP ROWAN” type motors are specifically designed to be controlled by tachometrically controlled
electroniccircuitsandtheirintrinsiccharacteristicsareespeciallysuitedtosupportrepeatedstart-upsurgesand
dynamicbraking.
Since they are brushless their maintenance is reduced to a bare minimum and normally merely concerns the
bearingsandchangingthetachometricdynamo,whichneverthelessmaybenecessaryafteraminimumof5000
workhours.
Changing bearings or tachometric dynamo
If the motor has to be dismantled to change the bearings, proceed as follows:
1- removethescrewsontherearfanhousingorscrollfanandslideitout,disconnectingthewiresontheservice
terminalblock
2- take out the tachometric dynamo
3- slide the stays out and remove the rear housing
4- remove the front housing that comes out followed by the rotor attached to it
5- ifnecessaryremovethefrontbearing,thedustguardscrewsandremovethesnapring(ifmounted)ontheshaft
6- slide the shaft out of the bearing
7- remove the snap ring (if mounted) that holds the bearing on the housing
8- slideoffthebearingandreplaceitwithanequivalenttype-ZC3versionlubricatedwithhightemperaturestringy
grease
9- the rear bearing must be type 2RS C3.
If necessary, replace the tachometric dynamo while assembling the motor.
Calibration of the air gap on the spring or direct brake
If a spring brake is mounted and the air gap requires calibration, proceed as follows:
1- remove the bolts coupling the motor to the brake hub
2- slide off the hub and brake off the shaft
3- remove the screws attaching the brake to the hub,
4- disconnect the brake cable from the terminal block
5- slide the brake off the hub.
At this stage the calibration can be made by adjusting the 3 bolts until an air gap between 0.2 and 0.3mm is
obtained. If the brake mounts a dustproof filter, remove it to access the calibration bolts.
Thespringbrakeissuppliedwiththemaximumbrakingtorque,whichcanbereducedbyunscrewingthespecific
crown to a maximum of 40%, always making sure not to unscrew it right out.
If the direct brakehasbeenmounted, thereis noneedto disassembleit,just controlthe air gap(maximum 0.3
mm) with a calliper through the side vents and if necessary correct it by slackening the grubscrew on the brake
hub.
Rowan motors require continuous ventilation and therefore it is essential that all the internal and external air
passagesinthemotorarenotblockedbyforeignbodiesandmoreoveranadequateairchangemustbeprovided.
InparticularlyaggressiveenvironmentsRowanmotors,whicharenormallyIP23,canmountadustprooffilterup

Themotorhasaheatsensorinthewindingsthatiscalibratedtotripat150°C(Rowanmotorwindingsareclass
H with a working temperature limit of 180°C).
The sensor gives a normally closed contact that opens at 150°C and has to be used to cut of the motor power
by a suitable relay switch in the event of an overload. The sensor will take a maximum load of 1A at 230VAC.
If the overload probe trips, check:
-thefanoperation
-a free air flow
-the motor absorption, if over the ID plate data, may be caused by excessive load or worn bearings.

Remember that in any case code 119/92-2HP board is necessary for the single phase motor 2HP Mec 100.
Replacing drive 119 with drive 119/92:
Withregardto powerconnections:
the wires previously connected to terminals 7 and 8 are to be shifted to terminals 11 and 12 of the code 119/92,
whereas the wires connected to terminals 5 and 6 are to be shifted to terminals 9 and 10.
With regard to control connections:

With regard to control wires connected to the lateral terminal strip of code 119:
- the wire connected to terminal NEG is to be shifted to terminal 1 of the code 119/92
- the wire connected to terminal AR is to be shifted to terminal 2 of the code 119/92
- the wire connected to terminal INV.TACH. is to be omitted (not necessary for the C119/92)
- the resistor connected to terminal REG. COPPIA must be eliminated.
Close microswitch S1 (for the other microswitches refer to the section containing the description of the
microswitches).

Forthepowerconnectionsproceedasfollows:
thewiresthatwereconnectedtotheterminals1and2aretobeshiftedtoterminals11and12ofC119/92,whereas
the wires connected to terminals 3 4 5 6 7 8 related to the capacitor and power and launching windings are to be
reconnected together as shown in the schematic.
For the control connections proceed as follows:
thetachometerwiresthatwereconnectedtoterminals9and10aretobeconnectedtoterminals7and8of C119/92,
whereas the potentiometer wires as follows: P-(OV), connected to terminal 11, must be shifted to terminal 6,
whereas P+, connected to terminal 12, must be shifted to terminal 5 of C119/92.
Forcontrol wiresconnectedto lateralterminalstrip M2ofboard C120/121proceed as follows:
shift the wire connected to terminal NEG to terminal 1 of C119/92;
shift the wire connected to terminal AR to terminal 2 of C119/92;
exclude the wire connected to terminal INV. TACH. since it is unnecessary for C119/92;
connectwire connected toterminal DECELto terminal5 ofC119/92.
Close microswitch S1 (for other microswitches refer to the paragraph describing the microswitches).
If a potentiometer is connected to terminal board M4 for torque limitation, you should reconnect it to terminals
1 3 4 of code 119/92 with 3 wires as illustrated in the schematic diagram; in this case close microswitch S2.
The circled numbers in the schematic refer to the terminals on C119/92.
